Subject: [PATCH v2 4/4] pwm: sunxi: Add H3 support
Date: Wed, 31 Aug 2016 17:25:20 +0900 [thread overview]
Message-ID: <20160831082520.25962-5-woogyom.kim@gmail.com> (raw)
In-Reply-To: <20160831082520.25962-1-woogyom.kim@gmail.com>
H3 PWM controller has same register layout as sun4i driver, so it works
by adding H3 specific data.
